Certein Bodies... Become Luminous When Heated. Their Luminosity Disappears After Some Time, But The Capacity Of Becoming Luminous Afresh Through Heat Is Restored To Them By The Action Of A Spark, And Also By The Action Of Radium.

It Must Be Done For Itself, For The Beauty Of Science, And Then There Is Always The Chance That A Scientific Discovery May Become Like The Radium A Benefit For Humanity.
